Node property settings missing when exporting the schema

[CAQ]

When exporting the schema from the web interface, the exported JSON file doesn't describe the following settings of node properties: Optional, Indexed, and Unique. As a result, when importing the schema from this JSON file, these settings are set to default values (false, false, false, or primary key: false, true, true).
Expected behavior: These settings are described in the JSON file.

It will be fixed in version 3.4.0, which will be released in one or two weeks.
